Opsimath

An opsimath is a person who begins, or continues, to study or learn late in life. The word is derived from the Greek ὀψέ (opsé), meaning 'late' and μανθάνω (manthánō), meaning 'learn'.

Opsimathy was once frowned upon, used as a put-down with implications of laziness, and considered less effective by educators than early learning. The emergence of "opsimath clubs" has demonstrated that opsimathy has shed much of this negative connotation, and that this approach may, in fact, be desirable.
